Hasbro Clue Jr. The Case of the Hidden Toys is a mystery-solving board game designed for children ages 5 to 8. Players take on the role of detectives tasked with finding out which pet has hidden which toy in the clubhouse. The game includes a game board, cardboard pieces, 5 orange bases, 5 green bases, pet and toy labels, a detective notepad, a die, and die labels.

To set up the game, players punch out the cardboard pieces and label the bases with pets and toys. They then place the clubhouse and fence on the game board and insert the bases into the fence. Players roll the die and move their movers around the board, collecting clues by landing on spaces with arrows or other players' movers. They mark their clues on their detective notepads by crossing out pets and toys that they find on the board.
